A little-known bug on GPS receivers saw many devices set the clock back to 1999 this weekend. This event, which takes place every 19. 7 years, has the potential to disrupt any system that relies upon GPS satellites for precise timing information.
TNW explained the bug in more detail a few weeks ago, but here’s a recap: GPS satellites transmit data and time information to terrestrial-based devices. Because the data packets are so small, the satellites are unable to encode this information in a standard DD/MM/YY format. Instead, they transmit a 10-bit number which counts upwards from an epoch.
